검증된 단계별 안내

Identify the type of survey conducted: This survey is based on voluntary responses from individuals who chose to participate, which is known as a voluntary response sample.

Understand the implications of a voluntary response sample: Such samples often lead to bias because they tend to attract individuals who have strong opinions on the subject, which may not represent the general population.

Consider the potential for non-response bias: Since only those who are interested in the topic are likely to respond, the results may not accurately reflect the views of those who did not participate.

Evaluate the representativeness of the sample: The sample consists of 1148 subjects who responded to an online question, but it does not ensure that these respondents are representative of the broader population in terms of demographics or opinions.

Conclude the main issue with the survey: The primary problem with this survey is the lack of random sampling, which results in a sample that is not representative of the entire population, leading to biased results.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Sampling Bias

Sampling bias occurs when the sample collected is not representative of the population intended to be analyzed. In this survey, the respondents are self-selected, meaning only those who chose to participate are included, which can lead to biased results as it may not reflect the views of the entire population.

Voluntary Response Bias

Voluntary response bias is a type of bias that occurs when individuals voluntarily choose to participate in a survey. This often results in a sample that over-represents individuals with strong opinions, as those who feel strongly about the topic are more likely to respond, skewing the results.

Non-Probability Sampling

Non-probability sampling refers to sampling techniques where not all members of the population have a chance of being selected. In this survey, the use of an online platform where participants self-select leads to non-probability sampling, which limits the ability to generalize findings to the broader population.
